Elastodynamic Finite Integration Technique Heterogeneous and Anisotropic Materials Image-based Modeling Ultrasonic Simulation
A straightforward simulation method is desired for the reliable nondestructive ultrasonic testing (UT). The target models for the UT become more complicated than ever, such as dissimilar welding parts in nuclear power plant or debonding parts of reinforced steels in concrete material. In this study, a time domain simulation tool for ultrasonic wave propagation in heterogeneous and anisotropic materials w ith a complex outer surface is developed by combining the elastodynamic finite integration technique (...

Finite Integration Technique Heterogeneous and Anisotropic Materials Image-based Modeling Ultrasonic Simulation
The ultrasonic testing (UT) of a dissimilar metal welding part is difficult due to the acoustic anisotropy and local heterogeneity. The ultrasonic wave in the weld is skewed along crystallographic directions and scattered by metal grain boundaries. Here we propose a straightforward UT simulation tool to predict wave propagation in the weld. The tool is based on the finite integration technique (FIT) and the image-based modeling. In our simulation, a picture of a specimen with a V-groove weld is scanne...
